When I power the monitor on the led turns green and the screen
illuminates and then quickly goes dark, but right before it goes dark I
see a 1" spectrum of many colors running vertically. then the led goes
to yellow. I have opened it up checked the board connections and see
nothing burned or discolored. when I power it on with the back open I
can see that the backlights are still illuminating for 3 seconds before
it turns off. I have tried it on several computers
using both the VGA and the DVI connection with multiple different
cables. This happened over the weekend and none of the other computers
had any problems so I do not know if this might have been a power
surge. Does anyone have any Ideas what might need to be fixed or

Re: monitor turns on then off quickly
From your description of the issue, the LCD and or hte inverter has failed. If less than a year old, contact Princeton Digital for warranty repair, if outside 1 year, it is likely cheaper to replace than repair

the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.
You can't always see where the solder is off .
Sounds like you need to purchase a new video card.
But before you do ,.. go into your control panel and reset everything in the display settings to original.
Advanced- DPI should be at 96 as default then check (drivers) roll back to original drivers (if you are running an ancient version of windows)
restart your cpu
If this doesnt werk ,... you have a bad monitor . ( hope you kept the reciept).
This is the way how to examine
what's wrong with your LCD monitors. After you turned your pc on, you have to check that if you can see the image on the screen or
not by shining a flashlight into the screen, not directly but find the best
angle to the screen and take a look very closely. If you can see the icons or
any image, there will be a minor problem. This is because of the lamps inside
screen. Some of them were broken and it is very easy to replace. If you cannot
see anything on the screen, there'll be some problems with inverter board. If you
have soldering tool and want to fix it by yourself, check the caps first. It
may cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
Hope this help!! If anything I can help you with, feel free to let me know. Thank you,
Looks like one of your backlights is bad, first indication is the red or pink tint, replacement of the lamp is fairly easy. If one lamp is bad the inverter will not work. You can get a replacement lamp from Mouser electronics for about $12
Try another power adaptor.
Check the delivered voltage and go get a universal power adaptor that has a switched for varios voltages and a number of connectors.
Simply match connector to the voltage switch.
